We are looking for a MySQL Query Optimizer to join our growing data engineering team. As a MySQL Query Optimizer, you will be responsible for analyzing, tuning, and improving the performance of SQL queries and database structures. Your primary goal will be to ensure that our MySQL databases operate at peak efficiency, supporting high-performance applications and data-driven decision-making.
In this role, you will work closely with software developers, database administrators, and data analysts to identify performance bottlenecks and implement solutions. You will use tools such as EXPLAIN plans, query profiling, and indexing strategies to optimize queries and reduce load times. A deep understanding of MySQL internals, indexing, and query execution plans is essential.
You will also be expected to provide guidance on best practices for writing efficient SQL, assist in schema design, and contribute to the development of automated tools for performance monitoring and optimization. The ideal candidate will have a strong background in database performance tuning, excellent problem-solving skills, and the ability to communicate complex technical concepts to non-technical stakeholders.
This position is ideal for someone who is passionate about data performance and enjoys working in a collaborative, fast-paced environment. If you are detail-oriented, analytical, and have a deep understanding of MySQL, we encourage you to apply.
